The circumference of a circular field is 163.28 yards. What is the radius of the field? Use 3.14 for π and do not round your ans

Alja [10]

Answer:

r = 26

Step-by-step explanation:

C = 2 π r

163.28 = 2 (3.14) (r)

163.28 / 2 / 3.14

26 = r

Answer:

segment IG ≅ segment LJ

Step-by-step explanation:

Please refer to the attached image as per the triangles as given in the question statement.

$\triangle HGI, \triangle JKL$

$G\left(-3,1\right),\ H\left(-1,1\right),\ I\left(-2,3\right)$

$J\left(3,3\right),K\left(1,3\right),L\left(2,1\right)$

Given that:

$HI\cong KL$ and

$\angle I \cong \angle L$

SAS congruence between two triangles states that two triangles are congruent if two corresponding sides and the angle between the two sides are congruent.

We are given that one angle and one sides are congruent in the given triangles.

We need to prove that other sides that makes this angle are also congruent.

To show the triangles are congruent i.e. $\triangle GHI \cong \triangle JKL$ by SAS congruence we need to prove that

segment IG ≅ segment LJ

Let us use Distance formula to find IG and LJ:

$D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$IG =\sqrt{(-2+3)^2+(3-1)^2} =\sqrt5\ units$

$LJ =\sqrt{(2-3)^2+(1-3)^2} =\sqrt5\ units$

Hence, segment IG ≅ segment LJ

$\therefore$ ΔGHI ≅ ΔJKL by SAS

What is the area of this figure?

Nina [5.8K]

Answer:

Area of the fig. = 127 yards^2

Step-by-step explanation:

So,Seeing carefully we see 3 figures : 2 rectangles & 1 square,

So, first of all Area of the Big Rectangle

Area of the rectangle = l*b

length = 13 & breadth = 9

= 13*9

= 117 yards^2

Now, Area of the small rectangle

Length & Breadth = 3 & 2

Area = 3*2

= 6 yards^2

Area of one and only square in the fig.

= S*S (side = 2)

= 2*2

= 4 yards^2

Total area of whole fig. = (117 + 6 + 4) yards^2

= 127 yards^2

Hope it works!
